HAY-RETARDING DEVlCE.

SPECIFICATION forming part Of Letters Patent NO. 710,967, dated. October14, 1902.

Application filed February 27, 1902. Serial No. 96.012. (No model.)

To @ZZ whom, it may concern:

Be itknown that I, HENRY GREEN, a citizen of the United States, residingat Pekin, in the county of Tazewell and State of Illinois, have inventedcertain new and useful Improvements in Hay-Retarding Devices; and I dohereby declare that the following is a full, clear, and eXactdescription of the invention, which will enable others skilled in theart to 1o which it appertains to make and use the same. This inventionpertains to a hay-retarding device for use on haying-tools, and relatesmore particularly to a device for attachment to the lifting-teeth ofhay-stackers. i5 An object of the invention is to prevent hay which hasbeen loaded upon the teeth of a stacker from slipping or being pulledfrom its proper position.

A further object is to provide a device for zo use on the lifting-teethof a stacker which will allow the hay to be easily deposited on suchteeth, but prevent it moving after being deposited thereon by thehay-rake.

Another object is to arrange an automatic device for the above purposewhich will pivot in such manner as to permit the hay to bev pushed uponthe stacker-teeth, but will rise by pressure of the hay against it andprevent a retrograde movement thereof toward the 3o points of the teethwhen the hay-rake delivering the load is withdrawn.

In the drawings herewith presented and which form a part of thisapplication, Figurek l is a side View of the lifting-teeth of ahaystacker, showing the loaded teeth of a eldrake in the act ofdelivering a load of hay upon the former. Fig. 2 is a perspective viewof a portion of a stacker-tooth, showing my device mounted thereon inits lowest position. 4o Fig. 3 is also a perspective view of the tooth,showing the device in its raised position. Fig. 4: is a side view of astacker-tooth, showing my device in section and in two positions. Fig. 5is a plan view of the lifting-head of a stacker, showing four of theretarding devices mounted thereon. Fig. 6 is a modified form of thedevice, showing the tooth in longitudinal section.

A represents a tooth of the stacker-head, upon which my retarding deviceis mounted, and which consists of a casting having a wing B at each sideof the tooth. Said wings' are of a triangular form, one corner of eachbeing pivoted to the tooth by means of apin O, which passes entirelythrough the tooth, each end passing through one of the said wings. Ateach of the outer extremities of the triangle is a cross-web D and'E, atthe top and bottom, respectively, as shown in Fig. 4:. In said figuretheretarder is shown in two posi- 6c tions and is free to rise and fallon its pivot for the purposes to be hereinafter described. Then placingthe retarder upon the tooth, the said tooth is pushed through the formerbetween the webs D and E. The latter are preferably beveled on theirsurfaces where they strike against the tooth, so that a iiat surface ispresented for contact. While I prefer this construction, I do not intendto limit myself to it, as may be understood. In 7o practice I make theportion of the retarder above the tooth project as little as .possiblewhen in its lowest position, as shown in Figs.

2 and 4, so that the hay may leasily slip over it when being placed uponthe teeth from the field-rake. The said retarder is pivoted high upon`the tooth, so that when it is'raised to the position shown in Fig. 3 andin Fig. 4c

in broken vlines it will stand quite high in order to present a largersurface to the hay 8o to prevent movement thereof.

I state above that the device consists of a casting; but it may also beformed by a sheetmetal punching, which will be as eiicient as thecasting, or said device may be formed in any other good manner known tothose skilled in the production of such arrangements. I do not confinemyself to the particulars shown and described, and the device may bealtered in a number of ways Without departing from 9o the spirit of myinvention.

As stated in the objects above, I seek to provide a device forpermitting the hay to be put upon the stacker-teeth and then prevent theslipping of the haythereon, andI do not wish to limit the same to anyspecied structure, since any form `or shape thereof Will-accomplish thedesired aim. As'an instance of the manner in which I may modify thedevice, I show in Fig. 6 a flat piece F in the loo form of an L, whoseshortest extremity is let into a slot G in the tooth and there pivoted.

The slot is of peculiar form, having a shoulder at I-I, with which saidshort portion contacts, and a face I supports the long arm, as shown.The use and operation of the form thus constructed is obvious from whathas gone before.

The operation may now be understood. As shown in Fig. l, the field-rakebrings a load of hay to the stacker and pushes it upon the teeth of thelatter and upon the retarders, which normally occupy the position shownin full lines in that figure. After the hay has been placed theheld-rake is backed away, and the hay naturally tends to follow it bythe friction between the hay and the teeth; but at this time theretarders come into use. The hay must, of course, in taking a backwardmovement bear against the said retarders, and since the point of contactbetween the hay and the retarder-s is above the pivotal point of thelatter said retarders rise to the highest position. (Shown in Figs. l,3, and 4.) Byplacingoneofthesedevicesupon every fifth, sixth, or seventhtooth, as shown in Fig. 5, the hay is easily held and all trouble causedby the sliding of the hay is averted. The retarders retain their raisedposition until the hay is ready for delivery upon the stack, at whichtime they fall by gravity to the lower or normal position; but if forany reason they should not reach the latter position the next load ofhay will push them down as it comes upon the stacker, as will be readilyunderstood.

In so far as I am aware no device of this kind has yet been used for thepurposes described. v

Therefore I wish to claim as my ownl. A hay-retarding device for use onhaying-tools consisting of a member supported on a stacker-tooth andadapted to rise and fall and adapted to permit the hay to pass over itin one direction as when loading but preventing movement of the hay inthe other direction for the purposes described.

2. A hay-retarding device for use on haying-tools which consists of amember pivotally supported on a stacker-tooth and adapted to rise andfall on its pivot whereby when in its lowest position hay may be pushedthereover and when raised the hay is prevented from moving toward thepoints of the teeth for the purposes explained.

3. A hay-retarding device for use on haystackers comprising a memberpivoted to a lifting-tooth of the stacker, the saine adapted toautomatically rise and fall on its pivot by the weight of the hay andthe force of gravity respectively for the purposes explained.

4. A hay-retarding device consisting of the side wings for straddling atooth and pivoted thereto, a stop at the top and bottom of the saiddevice for limiting the up-and-down movement thereof and arrangedwhereby the device is raised by backward pressure of hay against it forpreventing the hay slipping 0E the ends of the teeth and wherebyalso,lthe said device will fall by gravity after delivery of hay topermit loading.

5. A hay-retarding device consisting of the side wings B B, one at eachside of the tooth, the web D and E at the top and bottom respectivelyfor connecting said wings and forming stops for limiting the verticalmovement of the device, and the pivot-piu C for pivoting the wings to astacker-tooth to permit said vertical movements, in combination with atooth substantially as described and shown and for the purposes setforth.

6. A new article of manufacture comprising two parallel triangular sidesB B, there being a hole in one corner of each, said holes being oppositeone another, and a connecting-web between the said triangular sides atthe corners remote from said holes as set forth.

'7. In combination with the tooth of a haystacker, a device pivotedthereto to move in a vertical plane on its pivot, such device comprisinga body portion pivoted so as to normally lie at a lowest position by itsown weight, there being a stop on said device to limit its verticalmovements.

In testimony whereof I afx my signature in presence of two witnesses.

HENRY GREEN.
